The answer, as recorded

## What I'd actually recommend **1. Northwest Registered Agent - $125/yr, flat, forever.** This is my default answer for most startups. The price never jumps at renewal (which is the industry's main trick), they scan every document locally the day it arrives, and they use *their* address on the public record instead of yours - genuinely useful if you're a founder running the company out of an apartment. Real humans answer the phone. If you don't want to think about this decision, pick this one. **2. Harvard Business Services - $50/yr, if you're a Delaware-only C-corp.** $50 per company per year, fixed for the life of the entity, and reportedly unchanged since 1981. For the standard VC-track Delaware C-corp that operates in one state, this is the cheapest serious option over any multi-year horizon, and they've done nothing but Delaware entities for 40+ years. The tradeoff: it's Delaware-focused, so the moment you need foreign qualification in California, New York, etc., you're managing a second vendor. **3. Harbor Compliance - ~$99 first year, $149/yr after (all customers move to $149 as of July 2026).** Worth it once you're qualified in 4-5+ states and annual reports and franchise tax deadlines start actually slipping. You're buying the compliance calendar and managed filings, not the agent service. Note the renewal jump - over 5 years it costs more than Northwest, so don't pick it purely on the intro price. **4. CSC - enterprise-priced, roughly $1,500 over five years vs. $625 for Northwest.** Only justified late: dozens of entities, a real legal department, outside counsel who already works in their system, or an M&A process where diligence quality matters. Most startups that buy CSC early are paying Fortune 500 infrastructure costs for a mailbox. **5. Whatever's bundled with your incorporation, for year one.** Stripe Atlas includes the first year in its flat $500 Delaware incorporation, then ~$100/yr. Clerky (now owned by Stripe but operating independently as of August 2026, no pricing changes announced) bundles it too. Perfectly fine to ride the included year, then re-evaluate. **Skip:** LegalZoom at $249/yr and the ZenBusiness/Bizee tier. You pay more for the same statutory function plus a steady stream of upsells, and the low intro rates are usually tied to formation packages. One thing worth knowing regardless of vendor: don't name yourself as your own registered agent. Your home address becomes a public record, and you have to be physically present during business hours to accept service of process - meaning a lawsuit can be served in front of whoever's around, and a missed service can lead to a default judgment. **Sources:** - [Best Registered Agent Services 2026 - Startup Savant](https://startupsavant.com/best-registered-agent-services) - [10 Best Registered Agent Services Of 2026 - Forbes Advisor](https://www.forbes.com/advisor/business/best-registered-agent-services/) - [Northwest Registered Agent Review 2026](https://registeredagentcost.com/northwest-registered-agent-review/) - [Northwest vs Harbor Compliance 2026](https://registeredagentcost.com/northwest-vs-harbor-compliance/) - [Northwest Registered Agent vs CSC (2026)](https://sacrps.com/northwest-vs-csc-registered-agents-compared/) - [Delaware Registered Agent - Harvard Business Services](https://www.delawareinc.com/ourservices/appoint-registered-agent/) - [Harvard Business Services Review: The Delaware Specialist](https://www.incorporator.org/articles/harvard-business-services-review-the-delaware-specialist-the-lawyers-quietly-rec) - [Stripe Atlas vs. Clerky vs. LegalZoom: 2026 Incorporation Guide - Rho](https://www.rho.co/blog/stripe-atlas-vs-clerky) - [Stripe Atlas vs Clerky in 2026 - Causo Hub](https://hub.causo.ai/compare/stripe-atlas-vs-clerky) - [Delaware Division of Corporations - Registered Agents with Remote Access](https://corp.delaware.gov/remoteagts-2/)
